"ARLINGTON, VA. — Scores of farmers, politicians, engineers and refiners on Thursday blasted the Obama administration's latest plan for renewable fuels, with Iowa Gov. Terry Branstad accusing the White House of caving to Big Oil and turning its back on rural America."

"The Environmental Protection Agency has proposed requiring refiners to use 15.2 billion gallons of renewable fuels in 2014, 3 billion less than the amount written into federal statutes.

Although federal law forces U.S. refiners to incorporate an annually increasing amount of biofuels into the nation's diesel and gasoline supply, the EPA sets each year's specific volume obligations and can waive the statutory guideposts."
